Why will my laptop not start unless i reseat the processor?

[dalearyous]

basically i have a sony vaio laptop about a year old and everything works fine...when it turns on. when it doesn't ill hit the power button, lights light up and everything seems to be working fine except nothing happens. to fix this, i take apart the laptop and reseat the cpu and all of a sudden it works again. any ideas? i know this is kinda crazy but i would really like to fix this.

bad battery or cmos battery? A BIOS setting?

 

[dalearyous]

couldn't be battery because it still won't start with the battery out of the machine. bad cmos battery...maybe i don't understand why. yeah im going to reseat the cpu again and get it work and poke around in the bios and see if i can find something wrong. is it possible the motherboard is bad? ill also try and flash the bios as well.

when i got it working last night i ran memtest and pccheck and everything passed. just can't figure this out.

anyone else?

the cmos battery keeps all of your BIOS data intact when you turn the computer off. Some computer BIOS's will reset each time you shut the computer off without a cmos battery. Reseating the processor probably tells the BIOS something has changed and gives it the trigger needed to turn the computer back on. Other than that I would start looking for loose connections. You might have jolted something when you reseated the processor. I do find it weird you tear a computer apart and reseated the processor on a whim; I would have checked 20 different things before going that far.

Once you access the CPU, your warranty is toast. The laptop should be able to start minus the battery with the A/C adapter. Something's wrong there.

my warranty was toast a while ago. yeah i checked those 20 different things. i talked to all the guys i know who know hardware and did everything suggested and then reseated cpu. just didn't want to waist time with details. if the battery was dead...wouldn't the computer not keep time? cause it has no problem doing that.

i tried with or without the battery and same results.

EDIT, i just started turning the machine on and off to see what would happen. it worked a few times and then i got this blue screen message:
hardware malfunction
call your hardware vendor for support
NMI: Parity Check / Memory Parity Error
the system has halted

ok here is the wierd thing the memory passed memtest in this laptop and in another laptop...bad mobo?

edit** now it boots everytime but not into windows...gives me that message everytime

 

[dalearyous]

any idea

Bad motherboard/processor = new laptop

 

[dalearyous]

nooooooo

 

[btcomm1]

yesssssssssssssssssssssssssss


Yeah thats sucks, but looks like it probrably is the mobo.

 

[dalearyous]

hmmm sell for spare parts?

I know this is old thread, but all I could find concerning my problem...what are the 20 different things you would/did check before reseating processor?...

I am guessing it had nothing to do with reseating the processor. I am pretty sure the CMOS would have no clue you took the processor out and put it back in unless it was on at the time and that would probably kill it anyways. What is your problem anyways?
